The online Apple Store has always been one of the easier-to-navigate online stores from anyone. Like, ever!
Dell has always been the bastion of a billion choices, and a confusing mess.
That said, the last few years have been a bit confusing at Apple.com. The "follow the rabbit down the hole" method of discovering the "Buy" button has been bad. The new thing is better, but that "click for more" arrow thing has got to go. Stupid, stupid, stupid. Just put a thumbnail of the things on the front page and don't go making me click twelve times to find accessories.
